Image Aquisition with LabVIEW
Speaking of that, and new features and API, etc, etc, ...
any chance that there might be a new, updated version on the horizon?
Thanks for your kind words Mike
There is a lot of opportunity to expand my book, and yes, it's getting a bit long in the tooth (Vision 6.1), but I'm not planning a new version just yet for a couple of reasons:- There's still a lot of very useful information in the current version
- I've got several other projects on the boil that are demanding a lot of my time
- There's a bunch of exciting things going on at V I Engineering - it's a great place to work and I'm heavily (and happily) absorbed there for the moment
Now, if only I could squeeze a few more hours out of each day
I think a 30 hour day would just-about satisfy me... - There's still a lot of very useful information in the current version

When an event case is running I can't use other button like a stop before it end?
You've got your FP locked for that event case - unlock it and it will allow UI events:

Since the vision assistant is made by NI, wouldn't that be the logical place to look?
I think what you're looking for is actually called NI Vision Builder AI, and yes, it is a commercial product of NI's - you've got to pay for it.As an aside - for those out there that are into vision, the NI Vision Builder AI has certainly matured since the last time I saw it - we're currently using it on a visual inspection project and it is quite fully functional for process-type work. Rumour has it that version 3 is due out sometime soon and it'll be even better - well worth a look.
-
This can also be done with the standard picture VIs (which ship with most versions of LV) and can be found (at least before LV 8.0) in the Graphics & Sound palette.
Yep - that'll work too
-
I see this... National Instruments > Vision.
LabVIEW ships with a handful of basic vision functions under the "Vision and Motion" functions palette, but you can also get an add-on toolkit called the NI Vision Development Module. You can convert integer arrays to bitmaps, so all you need to do is create a low bit width (8 bit) image space (IMAQ_Create) and then convert your Booleans into integers (0/255), populate them into the image (IMAQ_ArrayToImage) and then save it our to a bitmap (IMAQ Write Bitmap File):
-
I want to convert this array full of '0' or '1' into a .bmp file with black and white pixels.
Do you have the NI-Vision Toolkit installed?

I also noted that when I received the packet and everything worked the "bytes to read" value I was getting was 5445, when it failed the value was 5450. So the failure was related to an extra 5 bytes of something (linefeeds or carriage returns would be my guess - something that caused at least one empty line in the middle of my data) getting placed at the 4097byte mark.
I'd love to see the actual data

"Are we there yet?"
"No!"
I had a friend that, when he was driving, if you said "are we there yet?", he'd always reply "yes - get out" - irrespective of the speed you were doing down the freeway

My father and uncle drove non-stop from Buffalo, NY to Miami FL in the late 1950s. To stay awake, the driver would place his fingers on the top of the window glass, then roll the window up to the top. If he started to doze off, his fingers would be pulled and wake him up.
There were obviously no ladies in the car, otherwise that strategy would never have been accepted

Dead? I get busy for a couple weeks and I feel like I lost touch with the planet. So what happened with Qubix?
I heard that NI has dropped the Qubix platform - maybe they found an existing COTS system that was comparable - might just be a rumour though...
PS: Welcome back Mike
We missed you! -
:question: Isn't cubix already dead?
-
Thank you! this is exactly that what I was looking for!
You're welcome

Thanks a lot! I gonna check it at home (I have labview 7 at home and 5 at work...)
Ahhh - I see. Well, you should be able to rebuild it from the following screenshots (essentially, it's similar to what you were doing, but with a picture control instead of a cluster):

I'm acquiring signals from 32 channels of four 4472 at sampling rate of 60k samples/s.So I'll have data of 2M samples/s(max).Will it be possible to display signal on time plot and can the same data be written in ASCII format?Is there any limitation on size of file?
You're posting in the wrong place - start your own thread.

ok! here it is...
Your post says you're using 5.1, but under your avitar it says you're using 5.1 & 7.1 - I don't have 5.1 on the PC I'm currently working on, so you'll have to live with this 7.1 version:
-
I often wonder how much work you actually get done?
Actually, it's Michael's fault! I used to check the LAVA forums once or twice a week, but since the appearance of the -All of LAVA- RSS feed, it turns up in a folder in my Outlook every 30 minutes (yeah, yeah - I know that's adjustable, but I just can't help it
)Good on 'ya, mate!Cheers mate, no w. furries - she'll be right cobber!

I tried the image cluster indicator (just pasted the picture in it) wired with a boolean in a case structure, and it is appeared when I pushed the button but dont want to disappear again when it was off...
Please post your example so we can help (either as a VI, or paste screen shots of the FP & BD).
-
Go to file> vi properties > security.
This won't remove the front panel - it only locks it from editing.
AFAIK, the only way you can remove a FP is to build the VI and select "remove FP" in the build settings...

Great challenge, and I'm happy to say that I've completed the basic part of my API and am thinking of some cool apps
That's what we like to hear - glad that it's stimulating your mind
The challenge states that my application HAS to use the same API as the test VI.The reason we chose a simgle API for all entries is that of a level playing field - as you can see from the announcement positing, there are a number of judges involved in selecting the final five, and we felt that placing this limit on entries allows us all to have a baseline - a frame of reference - to assess your entries on. For your entry to be valid, it must work with the template API, although once this is all over and the winners announced, by all means: go nuts! You might even find someone else's submission better than yours, which will give you an even better platform to create a new version from.
Both dynamic events and the mouse input VIs were not available in 6.1, so obviously there's no way to make it really portable in 6.1 without writing some external code.Although using the event structure and mouse input VIs are native to versions above 6.1, there may be methods that you can use to complete the tasks with 6.1 (I'm not saying there are, nor am I saying there aren't
). There are still plenty of people out there that are still using 6.1 (it is a pretty stable and functional version), and we didn't want to exclude those folks from entering the challenge. -

We LAVA you too, Chris!
Awwwwwww -
How long can he hold back...
I couldn't hold back any longer!
Thanks guys - I appreciate it. Another thing I appreciate is LAVA - it's a great place to hang out, with some top-shelf users and great discussions (it's my sanctuary from the real world
)Shameless plug: If you appreciate LAVA as much as I do, follow the link below...

Kia ora Paul! Please post any example VIs of things you've tried so far to we can point you in the right direction...
